Thanks for everyone's suggestions.
I had completely forgoten about BBS and ISP dialup numbers.
Will find one that works from the lists and run
Modemtest.exe and telnet when at the remote locations.
And some of them are VERY remote!

Today, EVERYTHING, goes through digitizaion at the telco.

Back in 70's, I found that the bandwidth was sharp edged at that '3kHz'
upper limit for any call that went thru a trunk line. But call across the
Bay Area? and you could easily shove a 10kHz square wave tone through the
phone connection.
